Based on the current conditions and situations, it is actually not impossible for Manchester United to win at Manchester City's home in tomorrow's match. But other results such as a draw are also very possible in tomorrow's derby match and I also won't be surprised if the home team wins the match because Manchester City has often lost in its important matches. As for Arsenal vs Everton, it will be a fairly easy match for Arsenal at their home because Everton is not a strong team this season in the Premier League.
With the match that will take place later, Manchester United can actually take advantage of their opponent's current condition because they are in a bad condition with their previous matches which always ended in defeat, making them lose their ranking above them and of course there is no clear certainty that they will be better in the next match, as well as with several injuries to Manchester City players such as one of their mainstay defenders who seems to be absent from tomorrow's match, it should be an opportunity for Manchester United to win the match.
I myself do not think this match will end in a draw, but what I think is that I doubt Manchester City can win the match, is it possible that they will be embarrassed at home? That could happen.
